When it comes to taking painkillers, why do some people get addicted while others do not?

A new study helps to identify who's at risk.

It found that the group most vulnerable to addiction has four main risk factors in common. Those include age, being younger than 65, a history of depression, prior drug abuse and using psychiatric medications.

Experts say the findings in the journal Addiction indicate that patients with pre-existing risk factors are more likely to become addicted to painkillers, providing the foundation for further clinical evaluation.
